A turbo fluid machine includes a housing, a rotating member, and a motor. Part of fluid compressed by a compressor impeller is introduced into a motor accommodation space through an inlet-side flow passage that has an inlet-side fixed throttle, and is discharged from the motor accommodation space through an outlet-side flow passage that has an outlet-side fixed throttle. The outlet-side flow passage includes a connection part connecting to the motor accommodation space. The connection part is formed separately from a clearance between a second partition wall and a shaft, and is located opposite to a connection part of the inlet-side flow passage connecting to the motor accommodation space across the motor in an axial direction of the shaft. The inlet-side fixed throttle and the outlet-side fixed throttle are configured such that pressure in the motor accommodation space is higher than pressure in a turbine-wheel back pressure region.

A centrifugal compressor includes a rotation shaft, a compressor impeller attached to one end of the rotation shaft, and a first wall surface and a second wall surface formed inside a housing so as to face each other in an axial direction. A diffuser is formed between the first wall surface and the second wall surface in the axial direction, and a wall portion separates the diffuser from an axial space inside the housing in which the rotation shaft extends. The wall portion includes at least one extraction hole that fluidly couples the diffuser to the axial spate and that is configured to extract a gas from the diffuser.

A foil bearing assembly includes a cylindrical body that defines a cooling fluid passage between a radial outer surface and a radial inner surface of the cylindrical body. The foil bearing assembly includes a foil bearing retained within the cylindrical body and in thermal communication with the radial inner surface of the cylindrical body.
